Greens are great but they still click, albeit a bit more quietly than Blues due to the increased actuation force required. As such, the keys might be tough to type on for long periods of time (definitely hard to sustain, I struggled to FPS game with them) unless your hands are used to pounding away on Model Ms.
How about linear switches? Blacks and Reds are nice for gaming and not bad to type on, but you will likely bottom out just as frequently as you do with the Blues.
Since you're just diving into mechanical keyboards, you won't want to deal with modifying switches (hint: desoldering and resoldering the entire board won't be fun unless you're an enthusiast).
